To all whom it may concern:

Be it known thatl, llnwano A. Groane- GAN, a citizen of the United States, residing at San Francisco, in'the county of San Francisco and State of California, have invented certain new and useful improvements in b5tenorsuperheatcrs; and I do hereby declare the following to be a full, clear, and exact description of the invention, vsuch as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

My invention rclatesto improvements in steam superhcaters, and particularly to such. superheaters constructed and combined with modifications of the lfostertype of marine boiler, and has for its objecti'nter' (dict the construction or" a supcrheater in such a manner and of suchshape and contour that it can be installed between upper and. lower banl-s of inclined water-tubes in sucliboilers. Another object of my invention is to so modify the common type of Foster ma rine boiler that it shall comprise two banks of inclined water-tubes connected with common headers; said. banks of tubes being spaced apart at such distance as will admit the installation of my improved superheater between them in such a manner that the tubes of the superheater will be acted upon as ell'ectively by the heat as are the boiler tubes.

These and other features of my invention are hereinafter fully set forth and explained and illustrated in the accompanying drawings in which Figure 1, is a side view of boiler showing an end View of my improved superheater installed therein, the side and base of the boiler setting being broken away.

2, is a top or plan view of my improved steam superheater.-

Fig. 3, is a view in elevation of one end thereof.

Fig. l,-is a View in elevation of the opposite end thereof.

Fig. 5, is a sectional. detail showing a side view in elevation. of the some installed in a boiler.

In these drawings, Fig. 1, A and A indicate the front and rear headers; B and B lower and upper banks oi inclined watertubcs connectin aid headers; C the steamdrum; 0 tubes connecting the steam-drum with the upper part of the rear header A: C tubes leading from the top or" the front header- A to the steam-drum C; D, D and D sections of the boiler setting, and l) the smoke exit therefrom.

()n thecentral part of the top of the lower haul: of tubes B, I secure a baille wall B leaving passages around the ends thereof for the passage of the heat upward; and under the upper bank of tubes B l secure bathe walls e'and .2 extending some distance inwardly from the front and rear headers A. and A, leaving a passage for the heat to pass upward through the upper bank of lines B; and on. the central part of the top of the bank of lines B I secure a ballie plate- F so as to-leave heat passages f and 7" past the ends thereof to the smoke exit D in the'space E between the upper and lower banks of tubes B and B upon suitable supportson the bafiie plate B l secure my improved superhcaterconsti acted substantially as follows end with an inlet 1', and. at the opposite end with an outlet 1 to be connected up with the steamsupply and output thereof in any convenient manner (not shown). The up per headers G and ll are connected by banks of tubes 5 and J and the lower headers by lower banks oi? like tubes, so that the steam travels from the inlet portion of "the header H, throughflthe tubes J to the header G at one side of the partition 9 therein, and thence through the tubes 9 to the lower header G, and thence through the corresnondinglower bank of tubes to the header H and thence longitudinally along the header H" and through the lower bank of tubes connecting it with the lower header G" at the opposite side of the partition g therein, and thence through the tubes g to the upper header G, and thence through the upper bank oi? tubes J to the header H at outlet side of the partition 7 therein, thus completing a circuit through all of the headers and their connecting tubes, from the inlet of the header H to the outlet thereof, thus continuously subwctmg the steam 111 its passage thereto to the heat applied to the headers and tubes comprising it in its prac' tical operation ;vand at the same time a compact and convenient installation thereof in a boiler of the type shown and described is mast plished, as is necessary in the installation of snperheaters in marine boilers of the type shown and described.

Having thus shown and-described my in vention so as to enable others to utilize the same, what I claim as new, and desire to secure by Letters Patent is The combination of a steam boiler having banks of'tubes spaced apart connecting the boiler headers 02? a superheater mounted in practically and effectively acconn.

said space comprising substantially a pair of centrally divided headers connected by short tubes, at one side of the boiler, a pair of headers at the opposite side of the boiler, one of Which is centrally divided, and provides the inlet and outlet of the superheater, and the other a continuous header, and banks of longitudinal tubes extending transversely tothe banks of boiler tubes connecting the headers in such a manner that there isa continuous steam passage therethrough,

and through the headers from the inlet to the outlet thereof, substantially as set forth In testimony whereof I afiix my si 'nature.
